The instrument, which is believed to have been played by band leader Wallace Hartley during the ship's sinking over a hundred years ago, will appear alongside other Titanic-related memorabilia in a special exhibition at Belfast's City Hall, UTV reports.

The display is part of events that will mark 400 years since Belfast's first Royal Charter was granted by King James in April 1613, giving it town status. Belfast didn't become a city until 1888.

City events officer Lisa Morgan said celebrations wouldn't be complete without the inclusion of the Titanic, which was built in Belfast.

"It's key to the history of our city and we'll have an exhibition that depicts the history of Belfast," said Ms Morgan.

"Belfast was granted town status in 1613 so it's quite a significant anniversary for the city and this is one of the key events. City Hall is going to open up for the four days from Saturday to Tuesday, from 11am to 5pm, and there's going to be an array of free activities."

Other events, such as tea dances, guided tours, film screenings and more, will be held at venues across the city over the Easter weekend.

The Titanic Centre will also be celebrating its first birthday this weekend.
